The EQuIS Live - Heatmap widget displays data in a tabular format. Data points in the chart are color-coded based on the range (lowest values to highest values) defined in the legend. The EQuIS Live - Heatmap widget provides a useful comparative visualization tool.
The widget contains two parts: a legend and a chart. The chart displays a tabular comparison of data points aggregated for a specified period over an interval of time.
The legend displays information about the range of the plotted data points and to which color the data points will be mapped. The legend can display in either list mode or gradient mode. Gradient mode will display a triangle indicator on the legend when a user hovers over a specific value in the chart.
To open the Widget Editor, select the More Options icon in the upper right corner of the Heatmap widget to open the drop-down menu and then select the Edit menu option. The widget properties are divided into two tabs: Heatmap and Options.
Widget Title – By default, the widget title is EQuIS Live - Heatmap. The title can be modified.
Widget Color – The color of the widget can be changed using the Change Widget Themeicon to the left of the widget title.
